Boka's first toothpaste for kids: Orange Cream Space Paste. "Boka's first official kid's flavor, Orange Cream, has vibrant notes of oranges paired with creamy natural vanilla. The name, Space Paste, is a nod to NASA's invention of nano-hydroxyapatite (nHa) in the 1970's. The ingredient, once only enjoyed exclusively by astronauts, is now available to junior space voyagers." Fluoride free & SLS free, $12 for 113g at Beautyhabit.
